CONCRETE-MIXER.

Specification of Letters Patent.

' 1 Application iua March 7, 1908. Serial No. 419,700.

To all whom it may concern;

Be it known that I, SAMUEL KNIsLEY, a subject of -King of England,residing at Phillipsburg, in the county of Phillips and State of Kansas,have invented certain new and useful Improvements in Concrete-Mixers, ofwhich the following is a specification.

This invention relates to that class of concreteunixers characterized bya rotatable receptacle in which the material is placed and mixed. Q

Theobject of the present invention is to provide a mixing rece taclewhich is so con structed that it can a so be utilized to carry thematerial to the place of use. The receptacle is rolled over the ground,and is, so constructed that this movement jars it sufficiently toproperly mix thematerial.

In the accompanying drawing Figure 1 is a side elevation of theinvention. Fig. 2 is a plan view. Fig. 3 is a longitudinal section.

Referring specifically to the drawing, 5 de-' notesa square box which isconnected to a frame comprising parallel longitudinal sidebars 6 andcross-bars 7. The box is rotahind the'cross-bars, to the opposite endsof I the box being secured journals 8 which are mounted in bearings 9 onthe side-bars. At the front end of the frame is a suitable device 10 forattachment of the draft animals.

The material to be mixed is placed in the box, and the latter is draggedover, the ground, it bein shaped on the outside so that it will rolandjar when it is thus dragged in order that the material on the insidemay be mixed. I

Access to the boxfor fillinglor emptying the same is had by making twoopposite sidewalls thereof removable. Each of said re movable side-wallscomprises two sections 11. To the outside of each of said sections aresecured stra s 12 having at their outer ends books 13 w" ich engageeyes-in the outer straps-also serve to strengthen the box.

ends of straps l4 securedto the outside, of

the adjacent sidewallsof thebox, '%%e e inneredges of the removablesections are engageab'le by-catches 15 ivoted to the end.

Walls ofthe box an sat inner edges are.re-' cessed as indicated at 16to-afiord a space for the catches to work in. f

To the outside of the'lsideuv-alls of'the box, near each. end thereof,are secured subsumtially triangular-shaped blocks 17 arranged edits toform a fiangesurrounding the box,

the

j which flange :by reason of the shape or the blocks has asubstantiallyoctagonal-shaped perimeter. This perimeter of the flange in contact withthe ground, and by reason 0 its angular shape, the box is given acontinuous jarring or shaking motion as itrolls over the ground so thatthe material therein is thor- -0ughly mixed.- The jarring and shaking ofthe box also prevents the -material from around by the draft animalsuntil the mate-. rial is properly 'mixed, and it is then hauled to theplace of use and dumped by removing and turning over the box by backingit.

For holding'the box stationary while it is being filled I rovide a brakedevice com: prising aslidear 18 working under guidewhich are engageableby the sli e-bar. In

is adapted t9 bestuck a pin 22 for locking the bar against longitudinalmovement,

, The brake device operates as follo'wsi The'supporting frame'of the boxlet down shown in 3, the box'being previously be engaged with thestop-block 20 as shown in Fig. 3.

and by reasonqfits engagement with the stop-block, ithe boxis: heldagainst rolling exceptto a'very smallextent not sufficient I rolled overthe ground, the slide-bar-will be sticking to the inside walls thereof.I The the sections 1], of one of the removable sides stra s- 19' securedto the cross-bars 7. 1011 ed sides of the-box 5 are sto -blocks 20:

said bar are holes 21 into either one of which;

The slide-barl is then locked by stickingthe in 22 through one of theholes 21 behind t e forward cross-bar 7'. This looks the bar againstoutward movementj.

retracted and held locked in this'iposition sticking the 22throughone-of theholes the,c atches 15. The box is then hauled 'sothatits front end rests on the ground as rolled forwardly so that theslide-bar 18 may forwardly. Rearward rollingv of the box,. 7

10.5. to interfere with the filling o eration, is PIG- ventedgby the enag'ement'o the end of the side-bar with the at side of the box adjacent" I the" stop-block. (When the box is being -1 11g y s'to lock. 7 Vv he apparatus herein described afiords convenient and efficient meansfor mixing -concreteor other material, it is sim le in construction andcan be easilyoperate and by reason of thefact that the receptacle canberolled to the place of use, there is considerable saving of time andlabor. The blocks 17 are shown and described herein as forming a flangehaving asubstantially 0ctagonal-shaped perimeter but I wish it to beunderstood that I do not desire to be limited to this shape. Theperimeter of the flange may have a different shape provided of *courseitis angular in order that the jarring had when 1t is rolled over the andshaking motion of the receptacle may be ground. Y I claim:

'A concrete-mixing apparatus comprising a supporting-frame, an angularreceptacle journaled therein, flanges surrounding said receptacle andhaving an angular perimeter which is in contact with the ground,stopblocks onthe outsideof the. receptacle, and a slide-ba carried bythe frame and adapted to engage the sto -block.
